Digital Zoom Area Position Detection and Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera systems do not adequately address the need to adjust the position of designated areas for focus and exposure settings when the viewing angle changes due to digital zoom, leading to issues such as blown-out highlights or overly dark images.
Innovation Solution
An information processing apparatus that includes a display control unit, an area designation unit, an enlargement unit, and a notification unit to determine and notify users if the designated area is outside the display area after digital zoom, allowing users to choose whether to move or maintain the area within the display range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If digital zoom is applied to change the viewing angle after area designation, then the display area shows an enlarged portion of the image, but the designated area may fall outside the display area causing loss of focus or photometry accuracy
Solution Approach 1:
The system performs preliminary determination to check whether the designated area will be within the display area before finalizing the zoom operation. This advance check allows the system to prepare appropriate notifications or adjustments, ensuring photometry accuracy is maintained while enabling quick zoom operations.
Solution Approach 2:
The system provides feedback to the user by notifying them when the designated area falls outside the display area after zoom. This feedback mechanism allows users to make informed decisions about whether to adjust the designated area or modify zoom parameters, thereby maintaining measurement precision without sacrificing operational speed.
2Ease of operation
If the designated area position is automatically adjusted after digital zoom, then the area remains within the display area, but user intent may be changed or overridden
Solution Approach 1:
The system dynamically adapts its behavior based on the specific situation. When the designated area remains within the display area after zoom, no action is needed. When it falls outside, the system offers the user a choice: automatically adjust the area or maintain the original designation. This dynamic approach provides ease of operation when needed while preserving user control flexibility.
Solution Approach 2:
The system enables users to self-determine the desired outcome by providing clear notification and choice. Users can decide whether to let the system automatically adjust the designated area or to manually reposition it, empowering them to maintain control over their imaging parameters while benefiting from automated assistance when convenient.
3Device complexity
If no notification is provided about area position after digital zoom, then the system operation is simple, but users cannot detect that the designated area is outside the display area
Solution Approach 1:
The system implements a feedback mechanism that notifies users when the designated area falls outside the display area after digital zoom. This notification provides critical information about the area position status without significantly complicating the overall system operation, allowing users to detect and correct potential issues with their photometry or focus settings.
